FRED J. KLINE, 01 NEW YORK, N. Y.

PAPER FASTENER.

Application Med May 2'6, 1924. Serial No. 715,798.

To all whom-it may concern:

Be it known that I, FRED J. KLINE, a citizen of the United States, residing in New York, in the county of Queens and State of New York,have invented certain new and useful Improvements in Paper Fasteners, of which the following is a specification.

This invention relates to paper fasteners and particularly to three piece 'flat file paper fasteners for holding letters, documents and various -other papers.

The main object of the invention is to provide a fastener of this type which has improved means for securing the members together. Another object is to provide a three piece paper fastener which is more easily and effectively operated than such fasteners which are now in common use. Still another object is to provide a paper fastener of this type that is especially adapted to be made in various sizes and which is simple and economical in manufacture.

The means I prefer to employ for effecting these objects, together with various other advantageous features of my improved paper fastenenare illustrated in the drawings accompanying and forming part of this specification, and in which- Figure 1 is a plan of a paper fastener embodying my invention attached to a portion of a file of papers.

Fig. 2 is a longitudinal section of the same taken on the line 2-2 of Fig. 1.

1g. 18 is a plan showin the final position of parts in the form of% ig. 17.

F g. 19 is a plan of another modification.

Fig. 20 is an enlarged plan of a portion of a paper fastener of the type of Figs. 17 and 18 showin means for locking the tongue covering mem er in its final position.

Fig. 21 is a partial longitudinal section of the same taken on the line 21-21 of Fig. 20, and

Fig. 22 is a plan of another modification of my invention.

Like character of reference indicate like parts in all the figures of the drawings.

Referring to Figs. 1, 2 and 3, the numeral 1 indicates a member provided with two spaced apart tongues 2 connected by a main portion 3. The said tongues 2 are pushed through a file of papers 4 and then through slots 5 in a retaining member 6 and finally bent down substantially horizontal on top of the member 6.

The member 6 has longitudinal ridges 7 near each of its side edges and projections or hooks 8 preferably struck up from the material of the member 6 so that a tongue covering member such as 9 can be slipped under them in a suitable manner.

The said covering member is provided with a bent down tongue 10 extending out lengthwise at the left hand end and is also provided with side slots or notches 11. To apply the tongue covering member 9, the tongue 10 is slipped into the left hand slot 5 in the retaining member 6 and pushed't'oward the left to the position shown in Fig. 2. The member 9 is then moved laterally so that the notch 11 at the middle part is slipped under the hook or projection 8 at the middle part of the member 6. Finally the member 9 is moved laterally in the opposits direction so that the notch 11 at the right hand end is moved underthe hook or projection 8 at the right hand end of the member 6. To remove the tongue covering member 9 the above-operations are reversed.

hooks 8 and then turned laterally so as to go under the books. The movement is a gyratin one. The width of the member 9 is slight y less than the spacing of the inner portions of the hooks 8. This allows the member'9 to be mo ed laterally enough to slip its right hand end under the right hand hook 8 into the final position as shown in Fi 4.

7 shows a modification of the principle disclosed in Figs. 4, 5 and 6. In this form two notches 1 1 are used and'these are long and have abutments or shoulders 12 on only one end andrelatively in reversed positions. The single hook 8 on the inner side of the member 6 is in this form nearer the left hand end than as shown, in Fig. 4. The operation of placing the cover is similar to that in Fig. 4.

In the form shown in Figs. 8, 9 and 10, the hooks 8 on the member 6 are arranged as in the form shown in Fig. 4 with the addition of a fourth hook 8 opposite the left hand one on the outer side. The member 9 has a bent down end portion 16 as more clearly shown in Fig. 9, and which is'usedto lock or secure the member 9 in its final osition. The said member 9 can be inserted in two ways, one of which is to slide it lengthwise throughout it'swhole length until the portion 16 is snapped into the position shown in Fig. 9, and the preferred way is to first insert the left hand end of the member 9 under the hooks 8, 8, at the left, the Width between bearing points of the hooks being greater than the width of the member 9, and then to move the member 9 laterally,

first under the middle hook 8, and finally 1n the reverse direction under the right hand hook 8 and placing the portion 16 inthe right hand slot 5 either by having it opposite the same in the last-mentioned movement or in finally moving it lengthwise of the fastener into said slot.

In the form of the fastener shown in Figs. 11 and 12, the member 1 is the same as in the previous forms 'but is .shown somewhat shorter, and'the member 6 has four oppositely-placed hooks 8. There is a downwardly-turned portion 16 onv the covering member 9 to hold it in its final position. The said member 9 isordinarily moved its entire length to place it in position under the hooks 8, and the portion 16 is brought 'to its final position by bending down the file and the end portion of the member 6 as indi- '9 has a projection or. tongue formed into a downwardly-extending hook 18 that is adapted to slip under the right hand end of the member 6, which is preferably provided niilth a recess 20 adapted to position it latera y. g

In the form of fastener shown in Figs. 17 and 18, the member 6 has three hooks 8 on the inner side and two hooks 8 on the outer side, opposite the end hooks on the inner side. The member 9 is provided with an upwardly-turned portion 22 at one end to move it, by. The said member 9 is placed in position by first sliding the left hand portion under the left hand hooks 8 as illustrated in Fig. 17 until the right hand end can move laterally inward past the outer right hand hook 8, thus bringing the member 9 under theinner middle hook. The said member 9 is then moved lengthwise under the right hand hooks 8 to'the final position shown in The form of the invention shown in Fig. 19 operates in the same Way as the form last shown, the difference between the two being that the greater length of the fastener of Fig. 19 allows the hooks 8 to be spaced slightly more advantageously as shown.

Figs. 20, 21 illustrate a downwardly-extending portion 24, which may be used in the last two forms, or in those of Figs. 4, 7, 8 and 11, in place of such portions as 16. An upwardly-turned portion such as 26 may also be formed in the retaining member 6 so that the portion 24 is not required to extend downward so far as it otherwise would. When the portion 24 is used with the form of fastener shown in Figs. 17, 18 and 19. the tongue covering member9 must be a trifle longer than ordinarily made, so that the piortion 24 shall come properly over the s 0t 5.

Fig. 22 illustrates a form of paper fastener in which the member 1 having the tongues 2 is similar to the foregoing forms and the retaining member 6 is similar to that of F i 11. The tongues 2 are shown in a condition where the file is of such thickness as to cause the projecting end portions of the tongues 2 to be very short and to come near the struck up hooks 8, so that it is very advantageous to form the tongue covering member 9 with portions 30 at each end, narrower than the remaining portion of the member, and said portions 30 are especially adapted to be passed in between the hooks 8, over the ends of the tongues 2, before the main portion 31' has come-between said hooks 8. Thus it is much easier to assemble the member, especially when the tongues it are unevenly bent. or rendered uneven on ac count of use.

What I claim is 1. A paper fastener embodying a member having a main portion and spaced apart tongues to be pushed through papers at right angles thereto, a retaining member having slots through which the prO ectmg tongue portions can then be passed and bent down on said member, and means for holding a covering member, a tongue covering member adapted to be held by said means, and means whereby the tongue covering member is secured in position on the retaining member by relative movements between said members and which movements include a laterally gyrating one and a limited longitudin'al movement.
